A young black man walking his girlfriend home through New York City's Central Park is accosted by a group of intoxicated white men. Words are exchanged and a fight breaks out, during which one of the white men is hit and dies. The black man is charged with manslaughter, but tells the judge that he doesn't want lawyer and will defend himself. The judge allows it but assigns Larry and Ken Preston to give him legal advice, even though he doesn't want it and in fact mocks the lawyers assigned to him and antagonizes the court during the trial.
When a patient bleeds to death during a routine hernia operation, his widow wants answers, yet she finds few forthcoming, so she asks Preston's help. The lawyer and his son work on the case, finding the doctors and staff of the hospital closing ranks, except for a young intern with a guilty conscience.
